I have finally tracked down what was going on here. The daemon only
fails to start at boot time when the action_mail_acct configuration
option is set. A look in the audit_config.c code reveals that the
email address is passed through the validate_email() function which
uses gethostbyname() to check the host. Although the network is up
before auditd starts, at that point in the boot sequence there are no
reachable DNS servers. This is due to a local configuration oddity
with the resolv.conf file. Moving auditd to later in the boot sequence
resolves the problem.
